I can highly recommend the 7mm-08 Rem as an alternative to the 308 Win. Both are excellent deer cartridges and I own both, but I love my 7mm-08 Rem. Great performance, light recoil and great accuracy. However, from what I have read about the 260 Rem it is also a great cartridge. I think you could close your eyes and pick any of the three and it would more than fit your needs. Ballistically they are all similar and the deer won' t really know the difference.
